Is there a social security agent in Weihai?

There is no such thing. There is, and it's unreliable.

Better handle it yourself. Now it's convenient to transfer with you in the same province in Shandong.

The process is: you go to Linyi, your father's pension insurance trust or unit (some are also in the human resources market) to open a transfer material, and then take these materials to the relevant pension insurance institutions in Weihai to settle down.

Pay attention to the payment period of social security pension (93 years ago is regarded as the payment period).
